Powerful Pulleys Students continue to explore the story of building a pyramid, learning about the simple machine called a pulley. They learn how a pulley can be used to change the direction of applied forces and move/lift extremely heavy objects, and the powerful mechanical advantages of using a multiple-pulley system. Students perform a simple demonstration to see the mechanical advantage of using a pulley, and they identify modern day engineering applications of pulleys. In a hands-on activity, they see how a Author(s): No creator set

Engineering in Sports Imagining themselves arriving at the Olympic gold medal soccer game in Beijing, students begin to think about how engineering is involved in sports. After a discussion of kinetic and potential energy, an associated hands-on activity gives students an opportunity to explore energy absorbing materials as they try to protect an egg from being crushed.Author(s): No creator set

Hilary Cremin et al. (2003) in their evaluation of the ways in which teachers and teaching assistants can work together in teams, suggest that, while there is enthusiasm for additional support, little attention is given to how this actually works in classrooms. It is true that learning support staff have been introduced into classrooms without clear research evidence that they can make a difference to children's learning, but then life often moves faster than the supply of research evidence.<

This unit has explored the social impact of psychology and provided a brief historical overview to explore the diversity of psychology as a discipline. You have read about the different kinds of data that are used as evidence and the different types of methods used to gather these data. You have also gained an understanding of the ethical issues that need to be considered when conducting research.

The material for this unit is taken from the introductory chapter to the course DSE212 Author(s): No creator set

What distinguishes psychological research from common sense is that psychologists approach information and knowledge in a systematic and consciously articulated way. They use rules and procedures about how to build and apply theories, how to design studies to test hypotheses, how to collect data and use them as evidence, and how to evaluate all forms of knowledge. (See Figure 1, ‘The cycle of enquiry’ in Box 1

A second kind of data is people's inner experiences, including their feelings, beliefs and motives. These cannot be directly seen from the outside; they remain private unless freely spoken about or expressed in some other way. Examples of these inner experiences include feelings, thoughts, images, representations, dreams, fantasies, beliefs and motivations or reasons. These are only accessible to others via verbal or written reports or as inferred from behaviours such as non-verbal communicat
